Anyone have good method of removing the film without

Hi Norm

I suspect the "decals" are more likely to be screen
printed with paint rather than hobbyist water transfers
unless they are on the back of a glass dial. If so, you
can probably use the standard method of surface cleaning
electical equipment, methylated spirits. You might like to
check a small spot of paint first.

I think it would be safer to try a solution of
dishwashing detergent in warm water first. This is
surprizingly effective and safe for most materials. Next up
would be a household cleaner like Formula 409. Any solvent
should be tested using a cotton swab on a spot that isn't
too visible. Rubbing alcohol may also work and is safe for
most paints and materials (but not cellulose nitrate or
acetate both often used for old dials and dial windows).
